Hi, I want to install the “back-off” brake light flasher on my 21 KR, but I can’t figure out the wiring on this LED 3rd brake light. I only need to know what wire feeds the brake portion.

I loved having it on my 18 Lariat and would appreciate any direction. The manufacturer was unable to help.
I just have to splice the module in between the 3rd brake wire. Thanks in advance.

Mechanics in the shop can tell you by looking it up in their Oasis Manual. Just ask. Otherwise, a test light should also do the trick

Should be pin #3 on the main connector. Easy way is to put a meter on it. Black is ground, the other two will either be the cargo or stop. Turn on the cargo lights and see if the orange or white has 12v.

Thank you again! It was the third pin(orange wire, black was negative. It flashes 5 times then holds.
